Network remote control technology refers to a computer (master) to control another computer (controlled), and when the master is on the control end, just as users sit in front of the controlled terminal, they can execute the controlled application and use the system resources of the controlled terminal.
VNC (Virtual Network Computing) is a set of software developed by the AT&T lab that can control remote computers. It adopts the GPL authorization terms and anyone can obtain the software for free. The VNC software consists of VNC server and VNC viewer. You must first install the VNC server on the controlled computer before you can control the controlled terminal on the control terminal.
(In windows, a set of well-known remote control software called pcAnywhere, is also released by Symantec.
VNC server and VNC viewer support multiple operating systems, such as Unix, Linux, Solaris, windows, and MacOS, therefore, you can install the VNC server and VNC viewer in different operating systems for control. If the current master computer does not have VNC viewer installed, you can control the control end through a general web browser.
The workflow for running the entire VNC is as follows:
(1) connect the VNC client to the VNC Server through a browser or VNC Viewer.
(2) The VNC Server sends a dialog window to the client, requiring that you enter the connection password and access the VNC Server display device.
(3) After the client enters the online password, the VNC Server verifies that the client has access permissions.
(4) If the client passes the VNC Server verification, the client requires the VNC Server to display the desktop environment.
(5) The VNC Server uses X Protocol to require X Server to assign control of the display to the VNC Server.
(6) The VNC Server will be sent to the client using the VNC communication protocol in the desktop environment of X Server in the future, and allow the client to control the desktop environment and input device of the VNC Server.
